Chapter 20.4, Problem 3CC
Summary Introduction
To determine: The lab tests and its results to rule out the presence of hepatitis A infection in the given patient.
Concept introduction:
To detect a known RNA sequence, methods such as reverse transcriptase polymerase chain reaction (RT-PCR) or RNA sequencing can be used. In both the cases, mRNA is first converted to complementary DNA (cDNA) and then analyzed. Hepatitis A is categorized as an RNA virus. Hepatitis A infection can be detected in the blood or tissue through these methods.

Wouldyou expect such particles to be infectious?arrow_forwardFinding drugs to treat viruses is far more challenging than finding drugs to treat bacteria. A. Why the difference? Ans: Viruses need a host cell to replicate and a bacteria needs food to continue to replicate. B. What can anti-viral drugs target in order to bring a viral infection under control, or to prevent a viral infection in the first place? Ans: To bring an infection under control you would want to inhibit protease so it could not break down the polypeptide protein chain down into new protein coats. C. What can anti-viral drugs target to prevent a viral infection in the first place? Ans: To prevent a viral infection in the first place you could take a medication that would alter the surface receptor, fill in the surface receptor or inhibits the viral surface protein all together. D. Offer 2 examples of drugs used to control viral infections (specify virus) and how do they work on different targets. Ans:…arrow_forward
